Deheubarth was a historical kingdom located in the southwestern part of Wales. It emerged in the early Middle Ages and was known for its rich culture and political significance. The kingdom was formed from the unification of several smaller territories and played a crucial role in the history of Wales during the 9th to 12th centuries. The name "Deheubarth" translates to "the southern part," reflecting its geographical position. It was ruled by various notable figures, including Rhys ap Tewdwr, who became a prominent leader. The kingdom eventually fell under the influence of the Normans in the late 11th century, leading to significant changes in the region's governance.
